Abstract
Described are new processes for making sustainable jet fuels and components thereof, based upon generating bio-ethylene by dehydration of biomass ethanol or a bio-syngas ethanol, and subsequently employing a tailored selection of oligomerization, cyclization, and hydrogenation reactions to generate each class of compounds which can be used as components in a sustainable aviation fuel. For example bio-ethylene oligomerization can provide olefin oligomers which can be hydrogenated to linear and branched paraffins, these paraffins can be cyclized to form bio-sourced aromatic compounds which subsequently can be hydrogenated to form cycloparaffins or naphthenes. These compounds can be blended to provide sustainable products in the kerosene jet fuel range (C8-C16) or wide-cut jet fuel range (C5-C15 or C4-C16).
